HistoryThe stem cells that have characteristic features of differentiation into stem cells that can divide further through mitosis and produce more stem cells. They are found in multi-cellular living things. In warm blooded cells, there are two wide sorts of stem cells: embryonic youthful cells, which are isolated from the internal cell mass of blastocysts, and adult stem cells, which are found in various tissues (Izadpanah et al. 2015). Stem …
Kochs PostulateFor many years, epidemics of contagious infections were believed to be as a result of the wrath of ancient gods, or miasma. German physician Robert Koch (1843-1910) helped in establishing a method useful in identifying a disease-causing agent. Koch’s postulate refers to the four criteria formulated in 1880’s to help in the determination of a causal relationship between a disease and its causative microbe (Inglis 200…

MethodsThe general aim of the experiment was to study myogenesis of C2C12 cells and investigate the appearance of Myosin Heavy Chain and proliferating cell nuclear antigen (PCNA) during differentiation and proliferation. This aim was achieved through several lab sections with different objectives. The first lab sections aim was to learn how to seed, culture and even differentiate and determine viability of C2C12 cells. Through the secon…

Clostridium tetani, a bacterium that can infect wounds exposed to soil or dirt is an endospore-forming, rod shaped bacterium that can cause tetanus. In Mary’s case she had got an open wound when working in her garden and this could have exposed her wound to the soil and also to the bacterium…

Cells, tissues, organs and systemsCells are the smallest unit of life, which is independent, composed of a cell membrane, genetic material, cell organelles and cell wall (in plants only). It is the key structural and functional unit of human body that makes up the complex human body structure. Cells are of two types, i.e. prokaryotes and eukaryotes. The prokaryotic cells are primitive cells, like bacteria, consisting cell membrane, genetic mat…
History or BackgroundHuman female germ cells has two X chromosomes and human male has one x and one Y chromosome. If the fertilization occurs via X-bearing sperm results in female offspring and fertilization by Y-bearing or X-deficient sperm results in make offspring. This ability of male gamete to determine the sex of the offspring and the presence of unique Y chromosomes in male gamete lead to the foundation of the paternal testing (Bachtr…
